This October, McDonald's Japan has been running a special sale: all French fry sizes are ¥150 per order. So ordering large sized fries, which are usually much more expensive, is now a bargain.

It's not just a bargain, though. It's also a French fry frenzy that's pissing some people off.

The French fry sale is leading to a handful of kids holding their own "Potato Party", in which they order absurd numbers of fries, and then upload the images to Twitter or their own blogs.

When the sale first started earlier this month, one Twitter user uploaded photos of 23 orders of large fries, which were then dumped into trays. Those trays became the feeding trough for kids to devour over 13,000 calories.

Kids are kids—they do stupid stuff everywhere. But McDonald's is slightly different in Japan. The McDonald's staff uses "polite Japanese" when they take orders. That isn't to say McDonald's is a fancy restaurant in Japan—but that Japanese people tend to have a much higher standard of what they expect in food service.

That in turn trickles down through the rest of the society, and there are much higher expectations towards how people should act in public. Not everyone feels this way, but the attitude does tend to dominate.

When the images of the 23 orders of French fries started getting re-tweeted thousands of times in Japan, many people criticized the teens for their silly stunt. Some said the teens were acting stupid and that this was a huge bother for this particular McDonald's, while others were amazed to see so many French fries.

One theme that continued to appear in the criticism was how wasteful the whole stunt appeared. "Look, buying 23 large French fries is fine, but you gotta eat them all, you gotta eat every last one," tweeted one individual.

In some cultures, you are supposed to leave some food to show that you are not hungry. In Japan, you are expected to clean your plate. Not doing so is seen as wasteful. And being wasteful in Japan is a sign of bad manners.

After the image (pictured above, via 秒刊SUNDAY) of 23 orders of McDonald's fries went viral on Twitter, others started having potato parties of their own, like this potato party in Osaka. Here are kids in Okinawa with forty orders of French fries.

And things seemed to have hit a fever pitch when a group visited a McDonald's near Okayama Station and ordered sixty large fries. They covered their table with trays and video game ads. The sixty French fry cardboard boxes were stacked up, and there was even a little pink balloon that announced their effort to consume sixty orders of large fries.

The photo gave the specific location of the McDonald's where the fries were ordered and was retweeted over ten thousand times in Japan in one day. Apparently, all the fries were gobbled up.

However, as Itai News points out, someone who's supposedly an employee of that McDonald's tweeted to the person who posted the photo, writing via Twitter, "Please stop, please stop".

The supposed employee added that other customers had complained. The issue seems to have been that the French fry eating went on for three hours, with the group eating sixty orders of French fries. It looks like one table was used for the feeding frenzy, while the adjacent walkway was packed with their friends who watched. Basically, the supposed employee seemed most upset about the lack of courtesy on their part.

What's more the supposed employee pointed out that sixty orders of French fries the roughly the equivalent of one home crate of frozen fries.

"Plus, during our restaurant's busiest period, 11am to 2pm, there was no prior notice about such a large order [from you], and this impacted what food and what tables we could offer to other customers." The supposed employee asked them to be aware of the time. Though, this McDonald's really should have been more aware of what would happen when a group of kids order sixty large fries.

The potato chaos wraps up on November 2 when the special ¥150 French fry sale ends.
